问一个关于RA卡片的问题

14.49 RA card
This card is used to define an ideal receiving antenna which is described by an impressed radiation pattern and which can be positioned anywhere in the model.
Read pattern data from: In this group the user must select one of four options:
• a *.ffe file: Read the radiation pattern from an *.ffe format file (which may be created with the DA and FF cards).
• an external data file: Read the radiation pattern from an ASCII file (the format of this file is described at the AR card (see section 14.17).
• after this line in the *.pre file: The radiation pattern is specified in the *.pre file following the RA card (the format isdescribed at the AR card (see section 14.17)). With this option
one can make use of the FOR loops to generate patterns from known functions.
• use last pattern defined at previous RA card: When using multiple RA cards (i.e. different receiving antennas in the same model) then it is quite common that the shape of the
pattern is identical. If this is the case, then one can load the pattern just once and at subsequent RA cards check this option here. Then the last defined pattern will be used and
memory can be saved (no need to store it again). Note that one is still able to set the antenna position and orientation individually.

这个我是看过多次了，不过好像还是不能解决问题啊，能再多介绍下么?

就一個 source ... 不知您的問題在哪?

不行就把模型发上来讨论 呵呵

仿真应用是没有问题的，就是对它的计算结果准确性有所怀疑，想通过理论验证下。
